AFAIR packet-ncp2222.c is generated with Python.
Even if Python is included in Cygwin, you need to install a different 
(native) version. I dont't know, why this hack is necessary, but it helps.

You can check, if I'm right at the size of the source files (packet-ncp*.c). 
If you have a 0-byte-file, you probably got it.
